Manthey Developing High-Downforce, Track-Focused Upgrade Kit for New Porsche 911 GT3 RS

Manthey-Racing is developing an upgrade kit for the new Porsche 911 GT3 RS. A spy video shows a test car attacking the Nurburgring.

The Manthey-tuned 911 GT3 RS looks similar to the standard model. Previous kits focused on aero and chassis improvements.

The stock 911 GT3 RS already produces high downforce. Manthey's kit for the regular GT3 added coilover suspension and shaved seconds off the Nurburgring lap time.

The new kit will likely have a bigger splitter, upgraded diffuser, new wing, and more based on past RS kits.

The upgrades will be expensive, possibly tens of thousands added to the GT3 RS's $225,250 base price. But it should make an already capable car even quicker.
